摘要
目的探讨Tei指数与室间隔缺损(VSD)患者肺动脉高压的关系。方法对55例单纯VSD患者,其中13例伴肺动脉高压,和26例健康人对照进行Tei指数测定。Tei指数分别从二、三尖瓣口和左、右室流出道的多普勒血流频谱测得。结果单纯VSD不伴有肺动脉高压患者的右室Tei指数与正常人比较无显著性差异。伴有肺动脉高压的VSD患者的右室Tei指数则显著增加(0.67±0.15vs0.28±0.06,P<0.0001)。右室Tei指数与右室收缩压(RVSP)具显著相关性(r=0.84,P<0.0001)。结论伴肺动脉高压VSD患者的右室Tei指数显著增加,且右室Tei指数与RVSP有显著相关性。右室Tei指数可提示VSD合并肺动脉高压的存在。
Objective To investigate the relationship of Tel index to pulmonary hypertension in patients with ventricular septal defect （VSD）. Methods Assessment of Tel index was performed in 55 patients with VSD （13 of which with pulmonary hypertension） by Doppler echocardiography and in 26 healthy subjects. Tel index was obtained by Doppler measurement from the mitral/tricuspid inflow and left/right ventricular （LV/RV） outflow velocity time intervals. Results Compared to VSD patients without pulmonary hypertension, those with pulmonary hypertension showed significantly increase in RV Tel index （0.67±0.15 vs 0. 28±0. 06, P〈0. 0001）. No significant difference in RV Tel index was found between VSD patients without pulmonary hypertension and healthy subjects. RV Tel index was significantly correlated with right ventricular systolic pressure （RVSP） （r=0.84, P〈0. 0001）. Conclusion RV Tel index was significantly increased in VSD patients with pulmonary hypertension, and RV Tel index was significantly correlated with RVSP. RV Tel index may thus be useful in predicting whether VSD patients also have pulmonary hypertension or not.
